Changes since 1.1: +9 -7 lines
update the intructions on how to run (in dir "run" instead of in "build"
 or "input" or elsewhere)

1 Tutorial Example: "P coordinate Global Ocean"
2 (Global Ocean Simulation at 4o Resolution in Pressure Coordinates)
3 ==================================================================
4 (formerly "global_ocean_pressure")
6 Configure and compile the code:
7 cd build
8 ../../../tools/genmake2 -mods ../code [-of my_platform_optionFile]
9 make depend
10 make
11 cd ..
13 To run:
14 cd run
15 ln -s ../input/* .
16 ln -s ../build/mitgcmuv .
17 ./mitgcmuv > output.txt
18 cd ..
20 There is comparison output in the directory:
21 results/output.txt
24 o the set up is similar to that of tutorial_global_oce_latlon
25 o the code directory contains calc_phi_hyd.F, where the potential is computed
26 according to the more natural finite volume discretization. Finite difference
27 discretization is energy conserving, but the representation of the "fixed"
28 surface (interface ocean-atmosphere) is less consistent.
29 o the code directory also contains dynamics.F which calls
30 remove_mean_rl.F, a generic routine, to remove the mean from the
31 diagnostic variable phiHydLow (sea surface height/gravity in pressure
32 coordinates)
34 changes: 07 Feb. 2003 (jmc):
35 o find difficult to maintain the local version of dynamics.F up to date.
36 therefore, has been remove from the code directory.
37 One can recover the same version (but up to date) simply
38 by activating the commented lines [between lines Cml( and Cml) ],
39 at the end of the standard version of dynamics.F
40 o finite volume form of calc_phi_hyd.F is now a standard option.
41 only needs to set integr_GeoPot=1 in file "data" to select this form.
